In the vast landscape of chemical additives, optical brighteners stand out for their ability to enhance visual appeal, making products appear whiter and more vibrant. For purchasing managers and product formulators, selecting the correct optical brightener is crucial for achieving desired results and maintaining cost-effectiveness. Among the many options available, Optical Brightener Agent SWN (also known by identifiers such as OBA 140 or MDAC) has carved out a significant niche due to its broad applicability and excellent performance. This article aims to guide you through the properties and applications of this versatile compound, emphasizing why sourcing from a reliable China manufacturer is a strategic advantage.

Optical Brightener Agent SWN is characterized by its high purity, typically around 99.50%, and its physical form as a white to light brown crystalline powder. Its melting point, ranging from 70-74℃, indicates its stability under typical processing conditions. A key advantage of SWN is its solubility profile: it is readily soluble in organic solvents like ethanol and ethylene glycol, as well as acidic aqueous solutions and resins, but it is practically insoluble in water. This property dictates its suitability for various applications where dispersion in non-aqueous or specific aqueous systems is required. For professionals looking to buy optical brighteners, understanding these solubility characteristics is fundamental to successful formulation.

The applications of Optical Brightener Agent SWN are diverse and impactful. In the textile industry, it is highly effective for whitening natural fibers such as wool and silk, as well as synthetic fibers like acetate, triacetate, and acrylic. It imparts a desirable blue-violet shade, enhancing the fabric's visual appeal. For plastic manufacturers, SWN offers a means to achieve superior whiteness in materials like PVC, contributing to a cleaner, more premium look for finished goods. Furthermore, its inclusion in laundry detergents significantly boosts the perceived whiteness of fabrics after washing, a key selling point for household cleaning products. The ability to purchase a single, effective agent for such varied uses makes SWN a highly sought-after chemical.
